Changing Element Icon in SysML v2

Hello,

 

Is it possible to change the element icons for SysML v2 models? For example the icon of a package in the containment tree etc.

Besides is there going to be an update for the Specification window of the elements? Compared to v1 models the Specification window is hard to navigate and not so successful to show the relations. Is there a way to maybe change the configuration of the Specification window?

Best regards

Safak
